2 Claims. (Cl. 219-70) This invention relates to metal disintegrators.

It is an object of the present invention to provide a metal disintegrator wherein means are provided for vibrating the nozzle against the metal so as to open and close the electron circuit of the device and to cut through the metal more effectively than heretofore; also, not subjecting the adjacent parent metal to heat and change in characteristic.

It is another object of the present invention to provide a metal disintegrator of the above type wherein the vibrating means is built into the disintegrator unit in a compact and easily operable manner.

Other objects of the invention are to provide a metal disintegrator bearing the above objects in mind which is of simple construction, has a minimum number of parts, is easy to use, is portable and efiicient in operation.

For other objects and a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a side elevational view shown partly in section and partly diagrammatically of preferred embodiment of the present invention.

Figure 2 is an enlarged fragmentary perspective view shown partly in section of the nozzle; and

Figure 3 is a side elevational view of this part, including the casing forming a part of the invention.

Referring now more in detail to the drawing, indicates generally a metal disintegrator including an air line 11 which terminates in the nozzle 12, a control valve indicated generally at 13 being mounted on the air line 11 and including the actuating lever 14, substantially as illustrated. An air hose 15 connected at one end to a suitable source of compressed air is connected to the inlet end of the air line 11 by means of the coupling 16.

An electrical conductor 17 is provided and connects with air line 11 by means of the T 19. Conductor 17 is connected to an electrical supply cable 20 by means of the connector 21. The air line 11 and nozzle 12, as well as the conductor 17 are constructed of electrically conductive material. The inlet end of the conductor 17 being connected to terminal 22 of the storage battery 23, by means of cable 20.

The metal to be disintegrated 25 is connected to the terminal 26 of storage battery 23 by means of the insulated conductor 27 (Fig. 1). Thus, whenever the nozzle 12 touches the material 25, the electron circuit will be closed, as will be obvious.

The conductor 17 is also connected to the inlet end of the air line 11 by means of the branch 28 and Ts 29 and 30.

A casing 31 is provided for the disintegrator, the forward end thereof being connected to the nozzle 12 by means of the adaptor 32 while the rear end of the casing is connected to the air line 11 and the conductor 17 by means of suitable connectors.

'An electric motor indicated generally at 35 is mounted below the air line 11 in suitable connection thereto, one terminal of the electric motor 35 being connected to the air line 11 by meansof the conductor 36. The electric motor 35 includes the casing 37, as well as eccentric means, not shown, mounted on the drive shaft thereof whereby to impart vibrations to the air line 11 and nozzle 12 when in operation. Said eccentric means may take the form of any'well-kn'own mechanical arrangement such as an out-of-balance armature for the motor 35 or a small adjusable weight mounted radially from said motor shaft. The other terminal of the motor 35 is connected to the terminal 26 of storage battery 23 by means of the control cable 38, a variable controlled rheostat indicated generally at 39 being connected in series with the motor 35 and including the manually operated knob 40. The variable controlled rheostat 39 is mounted in the case 31 to permit its operation externally. Thus, upon moving the knob 40 to the ON position of the variable controlled rheostat the motor 35 will operate the eccentric means and impart vibrations to the air line 11 and nozzle 12.

In operation the disintegrator 10 is held in the hand of the operator generally by placing the right hand about the lever 14 and through the finger hole shown in Figure 3. The left hand is then free to steady the tool and to manipulate the knob 40 on variable control rheostat 39, the nozzle is made to contact the metal 25, the-intensity of vibration is controlled by the setting of operable knob 40 on variable controlled rheostat 39 and it will be readily seen from a cursory glance at the drawings that as a result of the placement of motor 35 and handle portion of the tool the vibrations of nozzle 12 will occur in a semi-pivoting action about a pivot point adjacent the rear of the tool. In some instances, the rear of the tool may be rested on a bench or similar work surface. The temperature is controlled by the volume of air passing through valve 13 controlled by valve lever 14.

Whenever the nozzle 12 contacts the material 25 an electric circuit is formed. By employing vibration and air, a controlled disintegration of the material is accomplished.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

Having thus set forth and disclosed the nature of my invention, what is claimed is:

1. A light, compact, portable metal disintegrator tool for cutting and removing selected portions of hard metals and the like without damaging the surrounding material comprising an elongated main case member having therein an air supply line, a control lever for said air supply line mounted toward the end of said case away from the nozzle member, a finger hole cut in said case adjacent said control lever, coupling means at one end of said case for joining said line to an external supply of air, a hollow nozzle member connected to said supply line and extending outwardly of said case, the tip of said nozzle being disposed at an angle of approximately ninety degrees to the aXis of said case, a small diameter electric motor mounted within said case therewith, electric conductor means connected to said nozzle and said motor within said case, electric connector means mounted on one end of said case and connected to said conductor means for connection to an external electric current source, eccentric means mounted on said motor for unbalancing the rotor upon rotation thereof whereby said tool is vibrated in a semi-pivoting fashion about the end away from said nozzle member.

2. A' device as described in claim 1 including a rheostat member connected in series in between said motor and said electric current source whereby the speed of rotation of said motor may be controlled to vary the degree of vibration of said tool.
